WINDOW-CLEANER.

sPEoiFroATio'N forming part of Leeters'ratent No. 606,995, 'gated July5, 189s. Application filed Octoberl, 1897- 'Serial No. 655,306. `(Nomodel.)y

To all whom t may concern.-

Be it known that I, JACOB KIRCHMER, J r., residing at Cincinnati, in thecounty of Hamilton and State of Ohio, have invented anew and usefulVestibule-Cleaner, of which the following is a specification.

My invention is in the nature of a device for cleaning the snow and iceoff the windows of the vestibules of electric or other cars, and

xo has for its object to furnish the motorman with a device for thispurpose operating upon the outside of the glass, but provided With meansinside the vestibule for operating it.

lith this object in view my invention consists in the improvedconstruction, arrangement, and combination of parts hereinafter fullydescribed and afterward specifically pointedout in the claim. l

In order to enable persons skilled in the zo art to which my inventionmost nearly appertains to make and use the same, I willnoW proceed todescribe its construction and operation, having reference to theaccompanying drawings, forming part of this specication, in Which-Figure 1 is a perspective View of the interior of a vestibule of anelectric or other similar car. Fig. 2 is a fragmentary detail view,being a horizontal section through a portion 3o of the Window sash andframe on the plane passing through the center of the pivotal bar. Fig. 3is a detail vieW,.partly in elevation and partly in section, showing,onan enlarged scale, the inside of the frame in which the pivot is mountedand the adjacent Windowsash and cleaner. Fig.4 4 is a detail view, beinga vertical section through the window-- frame on the central line of thepivotal bar.

Like letters of reference mark the same parts Wherever they occur in thedifferent figures of the drawings.

Referring to the drawings by letters, A is the interior of a vestibuleprovided with the ordinary side and look-out Windows, the latter beingmarked B and being inclosed in the frame C.

D is the body or main frame of my cleaner, and it is provided on itsface With rubber E, which bears against the glass B of the lookoutwindow on the outside.

The frame C of the cleaner is secured by screws F to the bar G", whichis projected at a right angle from the pivotal bar H, mounted in thethimble I, secured in an opening in the Window-frame by means of screwsJ, passing through its flanged end K.

On the inner end of the bar H is provided a crank L for turning it, anda spring M, coiled around said bar,has its bearings against the [iangedend of the thimble I and a thin 6o peg N passing through the bar H. Thepin O passes through the ,bar H on the outside of the Window-frame andprevents the bar being pressed too far inward by the spring M.

In the operation of my invention the cleaner When properly set upwill bepressed against the outside of the glass of the Window B by means ofspring M, Whose normal tendency is by pressing against the thin peg tohold the cleaner thus in contact with the outside of 7o the glass. Byturning the crank L, Which is located, as shown in Fig. 1, Within easyreach of the hand of the motorman, the cleaner may be oscillated on thebar H ovei` the outer surface of the glass, thus removing all snoW andice therefrom.

The advantages attending the use of my invention are numerous and willbe obvious from the foregoing description.

As is Well known, the front or look-out Win- 8o dow mustnecessarily beclean enough to permit the motorman to see clearly ahead of the car.Otherwise the Window would have to be opened, to the great discomfort ofthe motorman in cold Weather. In such Weather the accumulation of snowand ice on the outside of the Window is such as to almost universallyrender it necessary in the most disagreeable Weather to leave the Windowopen. By the use of 'my invention all this difficulty is re- 9c movedand the motorman by simply grasping the crank from the inside and movingit in the arc of a circle can quickly and easily clean the outer surfaceof the Window, so that it may remain closed and protect him from theWeather.

W'hen myinvention is in place upon a vestibule and it is desired. toopen the Window, it is only necessary to turn the crank at right anglesto the position shown in Fig. l, which roo Will cause the cleaner to liein an upright position along the window, Where it Will not inA terferewith the opening of the Window or the removing of the sash. In turningthe cleaner to this positionV the motorman will press the bar Iloutwardly against the action of the spring M until the cleaner isremoved a sufcient distance from theoutside of the glass to swing clearof the Window sash and frame into its vertical position, as beforedescribed.

Vhile I have illustrated and described the best means now known to mefor carrying out my invention, I Wish it lto be understood that I do notrestrict myself to the exact details of construction shown anddescribed, but hold that any slight changes or Variations such as mightsuggest themselves to the ordinary lnechanic would clearly fall Withinthe limit and scope of my invention.
